In the aftermath, the University of Central Florida promised a year's worth of free credit monitoring and identity-protection services to anyone affected. The school recently released the following information:

12,210 -- an estimated number of people who accepted the credit monitoring.

$176,141.47 -- how much it cost UCF's insurance company.

The school's cybersecurity insurance also covered nearly $110,000 to communicate the security breach to the public, UCF documents released in March showed.

The FBI's Jacksonville office is investigating the UCF hack. Similar attacks have occurred at other campuses across the country, including one at Michigan State University this month.

When the hack was announced in February, UCF President John Hitt called on the school to do a "thorough review."

"To ensure our vigilance, I have called for a thorough review of our online systems, policies and training to determine what improvements we can make in light of this recent incident," he said in a news release.
